Abstract: A latch comprises a frame securable to a device enclosure, and a handle slidably secured to the frame, wherein the handle can slide between an inward position and an outward position, and wherein the distal end of the handle has a drive pin. The latch further comprises a rigid pawl having a latch key, a distal end pivotally secured to the frame, and a slot that receives the drive pin. Inserting the handle causes the drive pin to move within the slot, push the pawl toward a side of a chassis bay, and deploy the latch key into engagement with a slot in the side of the chassis bay. Withdrawing the handle causes the drive pin to move within the slot, pull the pawl away from a side of the chassis bay, and withdraw the latch key out of engagement with the slot in the side of the chassis bay.

Abstract: A latch selectively secures a compute node enclosure into a chassis bay. The latch comprises a frame securable to a proximal end of the compute node enclosure. A handle is pivotally secured to the frame intermediate a proximal end of the handle and a distal end of the handle so that the handle can be pivoted between a closed position and an open position. A proximal end of a pawl is pivotally coupled at to the distal end of the handle, wherein the pawl includes a landing at a distal end of the pawl and a latch key intermediate proximal and distal ends of the pawl. Movement of the handle positions the pawl into engagement with a slot in chassis bay to assist installation and removal of the compute node enclosure.

Abstract: A latch comprises a frame securable to an enclosure, and a handle pivotally secured to the frame for pivoting between a closed position and an open position. The distal end of the handle has a drive pin extending therefrom. The latch also comprises a pawl having a latch key, a distal end secured to the frame, and a proximal end coupled to the drive pin. Closing the handle causes the drive pin to move the pawl toward a side of the chassis bay and deploy the latch key into engagement with a slot in the side of the chassis bay. Opening the handle causes the drive pin to move the pawl away from a side of the chassis bay and withdraw the latch key out of engagement with the slot in the side of the chassis bay.
